Leverages advanced stress analysis (typically Finite Element Analysis) to evaluate complex geometries or loading conditions. This method focuses on protection against failure modes such as plastic collapse, buckling, and cyclic loading (fatigue). Key Differences from Division 1 Section VIII, Division 1 Section VIII, Division 2 Primary Approach Design-by-Rule Design-by-Analysis (Alternative Rules) Safety Factor 3.5 (standard) 3.0 (Class 1) or 2.4 (Class 2) Typical Pressure 15 psig to 3,000 psig No upper limit; generally > 600 psig Failure Theory Normal Stress Theory Von Mises (Distortion Energy) Certification Usually no PE required Requires certification by a Professional Engineer (RPE) ASME Section VIII - Inspectioneering
